Following up on posts by Jr, Dana, and Siddique, I'd like to add Ken Ham, President of Answers in Genesis, to the list of conservative commentators lacking shame and tact: 

We live in an era when public high schools and colleges have all but banned God from science classes. In these classrooms, students are taught that the whole universe, including plants and animals—and humans—arose by natural processes. Naturalism (in essence, atheism) has become the religion of the day and has become the foundation of the education system (and Western culture as a whole). The more such a philosophy permeates the culture, the more we would expect to see a sense of purposelessness and hopelessness that pervades people’s thinking. In fact, the more a culture allows the killing of the unborn, the more we will see people treating life in general as “cheap.”

I’m not at all saying that the person who committed these murders at Virginia Tech was driven by a belief in millions of years or evolution.[**really? THEN WHY DID YOU WRITE THAT LAST PARAGRAPH?] I don’t know why this person did what he did, except the obvious: that it was a result of sin. However, when we see such death and violence, it is a reminder to us that without God’s Word (and the literal history in Genesis 1–11), people will not understand why such things happen. 

The real criminals here? the separation of church and state, Roe v. Wade, and atheism. Outside of this being entirely untrue -- I'll point you to the work of  Gary Jensen, Steven Levitt, and, yes, Immanuel Kant -- Mr. Ham's little screed is profoundly insulting to the victims of Monday's tragedy. 

Ugh. Rule 1 of blogging: If you don't have anything constructive to say, shut the hell up.
